SPECI FIGATION forming pa.rt of Letters Patent N0. 233,024, datedOctober 5, 1880. Application filetl July 7, 1880. (Mo(lel.)

T0 all whom z't may concem Be in kn0wn that I, l/VINFIELD S. Romans, acitizen 0f the United Stntes, residing at (Jolnmbus, in the county 0fFranklin nn l Stnte ot" Ohio, hzwe invented eertain new a1nl nse fulImprovements in Lanterns; and I lo hereby declare the following 1:0 be nfnll, elear, and exaet deseription 0f the invention, such as will enable others skilled in the art to whieh it appertnins, to 1nake and usethe smne, reference being had t0 the aceompzmying drawings, and t0letters 01 figures 0f reference marked thereon, whieh form a pnrt 0fthis specifieation.

'lhis invention relates to hand-lanterns, und 1nore especially t0 thatdass of hand-lanterns used by railway-employ6s, and known as milway 01signal la-nterns.

One object 0f my invention is t0 eonstrnct an 0il-cup for such a lautemso filmt it will be independent of the lautem, but adnpted t0 beseenrely elamped between tl1e lautem frame und base when these pnrts arein position for use.

Another 0bject 0f the invention is t0 provide n eheaplyconstructed undefficaoious 1neans 0f warnning 01 heating the 0i1 in the ollcup duringcold weatlxer, so tl1at the wick may be kept well saturated with oil.

T0 these ends 1ny invention consists in providing the independent oileupWitl1 n fiange, which is elamped between the base and fra-nne 0f thelnntern wheu tlxese parts are eonnected f0r use.

It further consists in seenring t0 the wicktube 0r bn1ner 0f the oil-eupa wire, the mitl- (lle bent portion of which passes around the lower end0f the wiek-tube ancl dips into the oil in the cup, while the free endsterminate a little above the top of said wick-tube 01 burner.

It furtl1er consists of means by whieh the free encls ot' the wire maybe shifted laterally t0 bring them nearer t0 0r move them farther fromthe flame 0f the lmnp, as oeeasion n1ay require.

In the annexed dmwings, Figure l is an elevation 0f a railway-lanteru,dmwn pnrtly in seetion, t0 Show my improved construetion. Fig. 2 is aperspective 0f a lamp-burner bzwing my improved oil-heater attachecl.Figs. 3

t0 6 ihre detail views showing one method 0f adjusting the ends 0f theheater nearer to 01 fzwrther frorn tl1e flzune 0f the lamp.

The same letters 0f reference are nsed in all the figures in t-lxeinclieation of identieal parts.

The oil-cup A, prefembly 0f tl1e form shown, is provided ab the bottomwith a rigid fiange, A, which fits within a ring-flnnge, B, projeetingnpwardly fr0m the lantern-base B. 'll1e lower fing, c, 0f thelantern-frame O is of a size to fit snugly within t l1e ring-flnnge B,and is seeured the1ein by the studs c, pro jeet ing outwardly fron1 thelower fing, c, 0f the lantern-frame, wl1ieh studs enter nngular slotsfomned at opposite sides 0f the ring1flange B, ancl thus forrn abayonet-joint. One 0f the stnds 0 1nay be l0cked als the inner end 0fits slot by n spring, B t0 prevent the aeeidental sepnmtion 0f tl1elantern-frnme O an(l its base B. The lower ring, c. 0f the lm1tern-frameis 0f such size as t0 rest upon the flange A 0t tl1e oil-eup 01 la-mp A,whieh, being seated upon the web b of the hause B, will be secnrely heldin place when the lautem frame and bnse are attached, as shown inFig'. 1. The wicktnbe D 1's provided witl1 the ordinary serewenp D, f01'seeuring itin the neek ot' tl1e ollcup.

Tl1e bifureated heater adapted t0 wann the 0il consists of a l0op ofwire, E, the loop of which depen(ls .into the oil-eup some distancebelow tl1e lower end of the wiektube, With l'espeet t0 which the loopocenpies an angular Position, so that the lower end 0f the wick n1ay beeoiled up in the loop.

The screw-enp D of the wick-tube is provided 011 each side with slots d,rnnning ab 1ight angles t0 the Widtl1 0f the wiek-tube, and a1e offsetwith relation t0 eaeh other, es shown in Fig. 6. Seaced loosely wlthinthe serewenp D is a ezun-plate, G, having ezun-slots g and alargeopening, g, f0r the aecoxnmodation 0f the wick-tube. T0 the top 0f thescreweap is fixecl a slotted plate, F. 'll1is plante has slots f",arranged. similarly t0 the slots d in t-l1e bottonn 0f the sc1ew-eap. Ithas in addition tw0 segznental slots, ff, to provide f01' the 1novement0f the lugs g fixed t0 the eam-plate G, and intencled for operating theezun-plate.

A stud, f, projeets upwardly from tne plate F at a point about midway 0fone 0f the segmental slots f, the purpose of the stud being t0 lock oneof tl1e lugs g a1; either end 0f its range of motion in the slot.

Through the slots d, g, and f are passed the free ends 0f the Wim E,collars e being fixed thereto between the platesG anil F t0 prevent saidwire from slipping up 01 down. The free ends of the wire E am bent inehe manner shown, so that the points e will face and be directly acted0x1 by the radiated henta 0t' the fl2une. lhis curved construetion 0fthe euds 0f the loop 0f wire is 0f practical importance, because itavoids interfereuce with the flame when brought cl0se up t0 it-.

T0 further provide against such interference nf the heater-wire With theflame the ends 0f the wi1e stand askew, as shown best in Fig. 2, und areheld nskew b v the slots d n.nd f

Taking the position 0f Lhe parts as shown in l ig. 3, the adjnsting 0fthe heating-wire farther from the flnme is 2100011] plished by freeiugthe Ing fr0m the stud f und moving said Ing t0 the other end 0f its slotf. This causes n partial rotation of the cmn-plnte G, which, by thecmnlike action 0f its slots np0n the wire, forces said wire t0 the 0uterends 0f the slots d und f in the screw-cap und t0p plate. A reversemotion 0f the lugs and cann-plnte will, of conrse, produce an oppositeeffect.

In will be seen that by coiling the wick within the bent portion 01 100p0f the wire hezmcer the wick-tube and parts theretokmttached tube incase the 0i1 remaining in the cup chances to be stiff'ened 0x congealedby 001d.

I-I2Wing thus described my invention, what I cluim as new is 1. Thecombination, substantially as before sei: forbh, 0f the separate flangedoibeup, the base having an upwardly projecting ringflange, and lshedepending flange 0f tl1e lautemframe, adapted to be seoured within tberingflange of the base.

2. 'lhe combination, substantially as before set forth, of alle oil-cup,the wick-tube, and the bifurcated heater, 'uhe eurved ends of whichstand askew with reference t0 ehe said tnbe.

3. The combination, substantially as before sei; forth, 0f alle oil-eup,the wick-tube, and the bifurcated heater, arranged exteriorly 0f thewick-tube, said heater having a band at its lower end whieh standsacross and benezxth the lower end 0f the wick-tube.

4. The combination, substantially as before sei; forth, of the oil-cup,the sorew-cap, the wiek-tnbe, the bifurcated heater, and 'he 02mmplate,all constructed as described.

In testimony whereof I affix my signatnre in presence 0f tw0 witnesses.
